Abstract

The invention relates to a prestressed controllable flow-through limiting valve, especially a spraying valve with a valve piston which can move in a valve housing. The valve piston is subjected to the action of the pressure of a control medium on opposing sides, said pressure prevailing in a control chamber (16). In addition, the valve is subjected to the action of the pressure of the medium in a pressure chamber (11). Said pressure of the medium has a flow-through which should be controlled. The inventive flow-through limiting valve also comprises a sealing body situated between the control chamber (16) and the pressure chamber (11). The invention also relates to a spraying bar having a plurality of spraying nozzles to which a flowable medium is fed in a controllable manner. In order to improve said spraying valve, the invention provides that the control chamber and the pressure chamber are separated from one another by a metal bellow (22) provided as a sealing body.
